what injectors, software are you running?

04-18-2005, 06:36 PM
stock injectors, giac software on a k04, i put on my stock n75 and still nothin

u forgot to mention that u upgraded to a 5 bar

04-19-2005, 07:50 AM
you are definitely in the limp mode, get it vaged and we'll take it form there

04-19-2005, 08:12 AM
yep thats what im thinkin, gonna see if i can stop by the shop

04-19-2005, 08:24 AM
you can always disconnect the battery to erase the cel.

04-19-2005, 08:29 AM
i have no cel, but i just disconnect the battery and reconnected it and went for a spin and this is whats happining. when i give it gasthe boost goes to 10 psi, sputters for a second then it boost higher, do u think i just need to drive it more to let computer adjust

04-19-2005, 08:30 AM
hes not in limp mode bc that doesnt make ur car as he described fall on its face. he said its still boostin 10 psi if im not mistaken

04-19-2005, 08:33 AM
yea im pretty sure its not limp mode, i have no cel either. the car runs fine untill u give it gas enough to make it go to 10 psi then it spudders and it feels like crap

04-19-2005, 08:35 AM
bpv? did you upgrade urs?

04-19-2005, 08:38 AM

04-19-2005, 10:04 AM
did you do the throttle body adaptation

04-19-2005, 10:06 AM
check L hose for leak. Did it boost correctly when you had the stock fpr in?

04-19-2005, 10:08 AM
no it did not boost with the stock fuel regulator

04-19-2005, 10:36 AM
sounds like a leak to me...but maybe try a friends MAF to see if that helps??

04-19-2005, 11:27 AM
i gots no friends with audis but im going to dubwerks now, i will let everyone know what the prob was when i get back

04-19-2005, 01:59 PM
just pull the dtc's you might have a soft codes and those won't cause the cel to light up, trust me been there done that, same old story

04-19-2005, 06:11 PM
i went to dubwerks and they say it is a problem with spark. i just put the new densos in so im gonna change em out

04-19-2005, 06:25 PM
does your cel ever flash? and does the car shudder kind of bad when its boosting 10psi??

04-19-2005, 10:04 PM
yep kompressed you got it on the money. i changed out the denso plugs and put the old plugs back in(autozone didnt have replacement) and my problem is fixed. i need to still clear the codes and get new plugs

04-20-2005, 07:34 AM
Get the NGK ones from ECS!

04-20-2005, 07:57 AM
